A light emitting diode includes a first conductivity type nitride semiconductor layer, a V-pit generation layer disposed on the first conductivity type nitride semiconductor layer and having V-pits, an active layer disposed on the V-pit generation layer, a stress relief layer disposed between the V-pit generation layer and the active layer, and a second conductivity type nitride semiconductor layer disposed on the active layer. The stress relief layer and the active layer may be formed in the V-pits, as well as on a flat surface of the V-pit generation layer, and the active layer may emit light of a multi-band spectrum.
